Do IR models satisfy the TDC Retrieval Constraint?

St├ęphane Clinchant, Eric Gaussier
If it has been show in previous studies that most IR models satisfy most IR constraints, the situation of the TDC constraint is unclear, and the goal of this short paper is to show that several state-of-the-art IR models indeed do not comply with the general TDC constraint, but do satisfy the speTDC one. We will review here the recently intro- duced log-logistic model [2], as well as the Jelinek-Mercer and Dirichlet language models.
